Parathyroiditis
Parathyroiditis literally means inflammation of the parathyroid glands. Parathyroid glands are four small endocrine glands in the neck. These are parathyroid glands, and they secrete parathyroid hormone or parathormone.
PTH hormone[edit | edit source]
- Parathyroid hormone is the most important regulator of blood calcium levels.
- The hormone is secreted in response to low blood calcium levels, and its effect is to increase those levels.
Hypoparathyroidism[edit | edit source]
- Hypoparathyroidism, or insufficient secretion of parathyroid hormone, leads to increased nerve excitability.
- The low blood calcium levels trigger spontaneous and continuous nerve impulses, which then stimulate muscle contraction.
Causes[edit | edit source]
Most cases are caused by autoimmune process although other causes such as viruses can also be implicated.
Clinical course[edit | edit source]
Most of these cases are asymptomatic and self resolving.
